and Michael Peter DMareo, 6 Elmiieid Way, Sanderstead, England FiledSept. 15, 1960, Ser. No. 56,289 1 Claim. (Cl. 1ML-28) This inventionrelates to dumping barges, also known as muck barges, which are used fordumping material under water. @ne object of the invention is to providesuch a barge which can be used for illing in watercovered areas, such asgravel pits, up to and even above the water level.

According to the invention, a dumping barge comprises a pair of spacedparallel hulls and one or more hopper bodies mounted on the hulls abovethe load water line and adapted to discharge between the two hulls. Thehopper body or bodies may be operated by hydraulic rams and arepreferably of the clam shell type.

As the hopper body or bodies are mounted above the load water line,material can be discharged therefrom between the hulls up to and abovethe water level.

@ne embodiment of the invention will now be de scribed by way of examplewith reference to the accompanying drawings, in which:

FIGURE l is a side elevation,

FGURE 2 a plan View, and

3 is a diagrammatic cross-sectional elevation on line llllll of FIG. 1of a dumping barge.

ln this embodiment, the barge comprises two similar square-section hulls1, 2 constructed of welded steel plates on angle iron frames 3. Thehulls 1, 2 each have an inclined bow or forefoot 4 and an inclined stern5. A diesel engine 6 driving a propeller 7 and a hydraulic pump 3 ismounted in the hull 1. The rudder 9 and associated steering gear arealso mounted on the hull 1, and a control cabin 10 is mounted on theforward end of this hull.

Two hopper bodies 11, 12 of clam shell type are supported in bearings 13mounted on king posts or pedestals 14 bolted to the hulls 1, 2. Thehoppers 11, 12 are closed by pairs of hydraulic rams 15, 16. Each ram isarticulated to one half of the respective clam shell hopper body and toan anchorage 17 on the respective side deck. The rams are operated fromthe hydraulic pump 8.

The hoppers 11, 12 are disposed above deck level and well above the loadwater lin-e 18, as can be seen from FEGURE 3, so that they dischargethrough the space between the two hulls 1, 2 above water level.

The dumping barge which has been described is particularly adapted foruse in the sand and ballast trade for back filling gravel pits when theballast has been removed therefrom. The overburden which is removed fromthe top of the ballast in the part of the pit which is being excavatedis loaded by an excavator direct into the dumping barge, which thentakes it to the part of the pit which is being filled. The inclined bowof the barge is run ashore on the bank and the hopper is discharged. Thepit can thus be bacli-lled up to and above the water evel.

We claim:

A dumping barge comprising a pair of spaced, parallel hulls, at leastone clam shell type hopper body, at least two king posts each secured toboth of the said two hulls and carrying mountings for opposite ends ofthe two halves of said hopper body, said hopper body being thussupported above the load water line and adapted to discharge between thesaid two hulls, an engine accommodated in one of the said two hulls, apropeller driven by said engine, a hydraulic pump also driven by saidengine, a pair of hydraulic rams each of which is articulated to one ofsaid halves of said hopper body and to an anchorage on the respectivehull and is supplied with hydraulic duid from said hydraulic pump, and arudder and associated steering gear mounted on said one hull whichaccommodates said engine.
